v Patented Aug.' 3, 1920.'

Application led July 30, 1915, Serial No. 42,774. \B.enewed July 17, 1919. Serial No. 311,689.

To all 'whom it may concern Be it known that I, JOHN D. PEnEnsENLa citizen of the Unit d States, residing 1n Jackson, in the count. of Uinta and State of Wyoming, have invented certain new and useful Improvements in Autoloading Firearms, of which the following is a specification.

This invention relates more especially to that class of auto-loading firearms in which the loading and shell-extraction devices and the firing-train mechanism are operated from a power-slide that is actuated by the force of Athe powder gases transmitted through a rearwardly-moving member or device usually consisting of the cartridge-shell or a portion thereof.

My present improvements are adapted for use in firearms of various sizes and styles, including shoulder-arms of different varieties and calibers, and are particularly adapted,-especially as regards certain features of these improvements,-for use in those varieties of s and pistols which are commonly designated as auto-loading, and automatic Therefore, and in View of the circumstance that auto-loading pistols have become one of the more important branches of the firearms art, I have herein described and illustrated my invention as applied to, or embodied-in, a firearm of this class; and

in doing this I have, in the principal views,

shown the firing-train prov1ded with triggerdevices arranged for a non-automatic operation of the firearm, whereby a separate' pull -upon the trigver will be .required for each dischargepof t e arm.

A principal object of this invention is to furnish (more especially for use in arms of the classes described), simple and eiective mechanism for loading and firing, and to provide safety-devices and means so ari ranged, -and so controlling the loading, firing, shell-extracting and other devices and operational-as to secure a maximum degree of reliability in the operation of the firearm as a whole, and in the operation, individually, of the several elements, devices and vombmations which arecomprised therein.

For aiding inthe attainment of thesei results, one object of the invention is to furnish a breeching mechanism comprising-"Hf power-slide so arranged that the orce'ofthe!"` powder tothls s ide through a ri ld block or transmission member,y and wit out any intervenseswill be, or may be,transmitted ing long-stroke movement of said transmis.

sion member. Thus the block or transmission-member and the power-slide begin their rearward movement concurrently, and continue moving along together by an accelerated movement until the transmission member is halted by its engagement with the frame.

Y In my improved firearm, the complete mechanism, in addition to some framework suitable for receiving the several operatingparts and details, includes a barrel, a magazine, a breech action, anda compound mechanism whichf-considered as a whole,-I designate as" the [ire-control action, and which comprises two coacting mechanism trains, of which one is a firing-train, and the other is a controller-train, while each of these trains is also directly coperative with the breech action; and which also comprises in the preferable and more complete form thereof, Ya sear-actuatin trigger, a triggershifting controller-mem er, a controller-retracting Sear-member and a Sear-actuating firing-member. And one feature which is of a peculiar importance in my present invention, relates to an organization within this mechanism and arranged in such a manner, that the complex of coacting and operative members constitute a series of circuits each comprising a plurality of inter-acting members, and 1n which some members are comprised im several diii'erent circuitseach having, respectively, a diii'erent' function and a dii'ierent scope and range of action. For instance' the Sear-actuating trigger, the searmember' and that part of the controllermember which directly coacts with the sear, may be said to constitute a relatively short .three-member circuit in which each member operates by a direct action and reaction with eachof the other two members ofthe circuit. Simllarly, the trigger, scar, firing-member and controller, may be saidv to constitute one
